Previously, we installed Audio Waveform in the build image. That’s been moved to a build extension: 
import { defineConfig } from "@trigger.dev/sdk/v3";
import { audioWaveform } from "@trigger.dev/build/extensions/audioWaveform";

export default defineConfig({
  project: "<project ref>",
  // Your other config settings...
  build: {
    extensions: [audioWaveform()], // uses verson 1.1.0 of audiowaveform by default
  },
});
